I've just spent half an hour re-reading this, trying to find out info on aero wipers 
I'm sure I've read that you retro fitted facelift aero wiper arms but I'm starting to think I imagined it
Did you fit them? And if you did, how much were they and how do you rate them?
My current arms are looking a bit grubby and I have Bosch aero converted wipers on it but they don't really clear the edges properly. Do the facelift arms have the same problems?
